Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an interception device for wastewater treatment. Background Technology

[0002] Wastewater treatment refers to the process of purifying domestic sewage, industrial wastewater, and polluted natural water bodies through physical, chemical, and biological means to remove harmful substances such as suspended solids, organic pollutants, nutrients, heavy metals, and pathogenic microorganisms, so that they meet discharge standards or reuse requirements.

[0003] Interception devices can effectively intercept large particulate impurities in sewage, such as branches, plastic bottles, stones, and fibrous materials. Existing interception devices typically use a screen to intercept impurity particles in sewage. When cleaning the screen, a cleaning brush is usually used to clean the surface of the screen. However, the blockage inside the screen filter holes cannot be removed. The filter holes are blocked, which reduces the sewage flow area, and the actual treatment capacity is far lower than the design value. During peak periods, it is easy to cause sewage overflow risk. At the same time, the filter holes are blocked, which causes uneven stress on the screen. Long-term overload operation can easily lead to structural deformation or breakage. In addition, when intercepting impurities, it cannot crush the mud in the sewage. Mud is large and hard, and it is easy to get stuck in the screen filter holes, forming stubborn blockages.

[0004] Therefore, it is necessary to provide a new interception device for wastewater treatment to solve the above-mentioned technical problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 As shown, a sewage treatment interception device includes a water channel 1 and a fixed frame 2. The fixed frame 2 is fixed to one side of the water channel 1. A driving component 3 is provided inside the fixed frame 2. A rotating rod 4 is rotatably connected to the inner wall of the fixed frame 2. A crushing roller 5 for crushing mud in sewage is fixed to one side of the rotating rod 4. The driving component 3 can drive the rotating rod 4 and the crushing roller 5 to rotate. The crushing roller 5 can crush the mud in sewage and prevent large mud from clogging subsequent treatment equipment.

[0025] The mounting frame 6 is fixed to the inner wall of the water channel 1. A grating plate 7 for intercepting and treating sewage is inserted into the inner wall of the mounting frame 6. The grating plate 7 can be installed by inserting it into the mounting frame 6. The grating plate 7 intercepts and treats sewage, removing large particles and suspended solids from the sewage. Two sets of support frames 8 are fixed to the top of the water channel 1. Lifting components 9 are provided on the top of both sets of support frames 8. The lifting components 9 can drive the grating plate 7 to be raised and lowered, which facilitates the subsequent disassembly and replacement of the grating plate 7.

[0026] The guide rod 10 is fixed to the inner wall of the water channel 1, and one end of the guide rod 10 is fixed to one side of the mounting bracket 6. A connecting plate 11 is slidably connected to the outer side of the guide rod 10. A push rod 12 for clearing the grid plate 7 is fixed at the bottom of the connecting plate 11. By pulling the connecting plate 11 to slide on the outer side of the guide rod 10, the push rod 12 is inserted into the grid plate 7 to push out and clear the blockage.

[0027] The driving component 3 includes a first motor 31 fixed to the top of the fixed frame 2. A threaded rod 32 is fixed to the output end of the first motor 31. A toothed plate 33 is threadedly connected to the outer side of the threaded rod 32. The outer side of the toothed plate 33 is slidably connected to the inner wall of the fixed frame 2. Multiple sets of gears 34 are meshed on the outer side of the toothed plate 33. The shaft of the gear 34 is fixedly connected to the outer side of the rotating rod 4. The first motor 31 drives the threaded rod 32 to rotate, causing the toothed plate 33 to slide on the inner wall of the fixed frame 2 and move vertically up and down. The movement of the toothed plate 33 drives the multiple sets of gears 34 to rotate simultaneously, thereby driving the rotating rod 4 and the crushing roller 5 to rotate, thereby crushing the sludge in the sewage.

[0028] The lifting component 9 includes a housing 91 fixed to the top of the support frame 8. A second motor 92 is fixed to one side of the housing 91. A winding roller 93 is fixed to the output end of the second motor 92. A pull rope 94 is provided on the outside of the winding roller 93. There are two sets of pull ropes 94. One set of pull ropes 94 is fixed to the top of the grid plate 7. The second motor 92 drives the winding roller 93 to wind up the pull rope 94, so that the pull rope 94 pulls the grid plate 7 to slide inside the mounting frame 6, which is used to raise or lower the grid plate 7, so as to facilitate the installation, disassembly and cleaning of the grid plate 7.

[0029] A cylinder 13 is installed on one side of the water channel 1. A guide frame 14 is fixed on the top of the connecting plate 11, and one side of the guide frame 14 is fixedly connected to the piston rod of the cylinder 13. The cylinder 13 is composed of an air compressor, an air tank, a filter pressure reducing valve, a directional control valve, and a flow control valve. In use, the air compressor compresses the ambient air to a set pressure and stores it in the air tank. The filter pressure reducing valve further purifies the air and stabilizes the pressure. The air is then delivered to the control valve through an air pipe. The directional control valve switches the airflow channel according to an electrical signal to determine the extension and retraction direction of the cylinder 13. The flow control valve adjusts the airflow speed and controls the movement speed of the cylinder 13. Compressed air enters the rodless chamber or rodless chamber of the cylinder 13, pushing the piston to move. The piston drives the piston rod to output linear reciprocating motion. This is existing technology and will not be described in detail here. By starting the cylinder 13, the guide frame 14 is pulled to move, causing the connecting plate 11 to slide on the outside of the guide rod 10, so that the push rod 12 is inserted into the inside of the grid plate 7 to push out and clear the blockage.

[0030] A limit rod 15 is fixed to the inner wall of the water channel 1. A guide block 16 is slidably connected to the outer side of the limit rod 15. A collection box 17 for collecting impurities intercepted by the grid plate 7 is fixed to one side of the guide block 16. A scraper 18 for cleaning one side of the grid plate 7 is fixed to the inner wall of the collection box 17 by bolts. A pull rope 94 in another set of lifting parts 9 is fixed to the top of the collection box 17. The collection box 17 achieves the effect of collecting impurities intercepted by the grid plate 7 and can also collect impurities cleared by the push rod 12. The collection box 17 is pulled up by the pull rope 94, which drives the guide block 16 to slide outside the limit rod 15, making it convenient to remove and clean the collection box 17 later. The movement of the collection box 17 drives the scraper 18 to scrape and clean the adhesive on one side of the grid plate 7, improving the cleaning effect of the grid plate 7.

[0031] A limiting frame 19 is fixed to the inner wall of the water channel 1. A baffle 20 is slidably connected to the inner wall of the limiting frame 19. Multiple sets of baffles 21 for diverting sewage are fixed to the inner wall of the water channel 1. When the baffle 20 is inserted into the water channel 1, the sewage inside the water channel 1 can be guided. The baffles 21 can be used to divert sewage, so that the sewage is more evenly distributed in the entire water channel 1, thereby improving the treatment efficiency.

[0032] Working Principle: In use, the first motor 31 drives the threaded rod 32 to rotate, causing the toothed plate 33 to slide on the inner wall of the fixed frame 2. This allows the toothed plate 33 to move vertically up and down. The movement of the toothed plate 33 drives multiple sets of gears 34 to rotate simultaneously, thereby rotating the rotating rod 4 and the crushing roller 5. This crushes the sludge in the sewage. The grating plate 7 is then inserted into the mounting frame 6 for installation. The grating plate 7 intercepts and treats the sewage, removing large particles and suspended solids. The second motor 92 drives the winding roller 93 to wind up the pull rope 94, causing the pull rope 94 to pull the grating plate 7 to slide inside the mounting frame 6, raising or lowering the grating plate 7 for easy installation, removal, and cleaning. The collection box 17 then collects the grating plate. The grid plate 7 effectively intercepts and collects impurities, and can also collect impurities cleared by the push rod 12. By pulling the rope 94, the collection box 17 is raised, causing the guide block 16 to slide outside the limit rod 15, facilitating the subsequent removal and cleaning of the collection box 17. The movement of the collection box 17 also causes the scraper 18 to scrape and clean the adhesive on one side of the grid plate 7, improving the cleaning effect of the grid plate 7. By starting the cylinder 13, the guide frame 14 is moved, causing the connecting plate 11 to slide outside the guide rod 10, allowing the push rod 12 to insert into the grid plate 7 to push out and clean the blockage. The baffle 20 is inserted into the water channel 1 to guide the sewage inside the water channel 1. The partition 21 can be used to divert the sewage, making the sewage more evenly distributed throughout the water channel 1, thus improving the treatment efficiency.
